The structure of sperm
Sperm into an egg cell before
() At the independent newspaper "13 reported, compared with fundamental research, Woody Allen in the erotic · Canon law about a touchy of sperm of first-class description more humor based on his innate intuition. But now scientists have claimed that they first discovered the male germ cells of complex work.
According to a new study, sperm far and sex (male DNA delivery to the female egg of simple means) of the insignificant contribution of, and food science in six-course meal (the equivalent of asix-course gastronomic meal) have the same meaning. Scientists have identified several hundred kind of male body composed of the smallest cell — the sperm of the head and tail of the protein, sperm is so small that a teaspoon to accommodate approximately 5 million sperm. They believe that these proteins can make people more aware of the following two issues: how to complete the sperm is equivalent to the Atlantic Tour of the eggs close to the process, and how it is possible to reach the egg of the first competitors of efforts for interference.
United Kingdom Paz University biologists Tim · Kerr said the sperm of protein structure from forced and it is also the cause of male infertility and sexual evolutionary origin. Dr. Kerr said: "if we can make a sperm sperm more successful than others, maybe we can use this knowledge to the sperm insufficiency treatment made reasonable analysis. "This study published in the journal Nature Genetics ·, they passed on Drosophila melanogaster sperm finished the research, but scientists believe that they identify the 381 protein in half or in human sperm cells found.
Researchers plan through the experiment reveal different species (including human) sperm protein components. Dr. Kerr said: "this is for any organism of sperm protein of the first directory, we first need to answer some of the most basic biology, it provides a general framework. Surprisingly, we on the internal structure of the composition of sperm almost nothing, no matter how the evolution of sex, which perhaps is why can't we truly understand the nature of the cause. "Until now, scientists know that very few sperm cells comprising of biological molecules of protein composition. Kerr says, if you know all the protein (proteins) will be unlimited extension of our knowledge. He said: "be different species of sperm of protein structure and composition of the group for comparison should help us understand the origin and evolution of sperm. "Biologists believe that sperm have evolved a set of very sophisticated mechanisms used to interfere with other competitors, reduce their first opportunity to reach the egg. Dr. Kerr said: "for many years, the sperm competition issues have always been perplexed with scientists. ”
The University of bath · Theodorus of Steve participated in this study, he said, understanding the protein composed of sperm cells will address other human secrets in a critical way. He said: "sperm sperm for Proteomics research necessary for sport (swimming ability), fertilization and possible early embryonic development, and other key function composition provides the Foundation. In infertility research, it should be a very valuable tool, now there will be more objective research based on the typical organisms. Now we can start looking for the ' core ' sperm proteins, they are a necessary component of sperm in the most basic elements. This not only shadow out evolutionary origin of sperm, it may also be able to deepen our sexual understanding evolutionary process itself. ”
About the interesting data: sperm
1. sperm production in the testes, sperm require approximately 10 weeks to reach maturity.
2. mature epididymal sperm storage.
3. sperm is the smallest cells in the body, it requires the ability to balance.
4. the temperature must be lower than 3-5 degrees to produce large amounts of healthy sperm.
5. an adult male daily produces 70 million-1.5 million sperm.
6. at the cutting-edge of erectile Yang, about 300 million sperm.
7. the ejaculation process sperm movement speed of up to 28 miles/hour.
8. epididymal sperm through the vas deferens in transmission, the vas deferens is enriched with fructose fructose liquid, the equivalent of rocket fuel, helps sperm transport.
9. it 12 inches per hour tour.
10. most of the semen is an alkaline substance that helps sperm journey.
